median shade band, and discal spots on both wings. Primaries blackish powdered 

 on costal area. Expands 1. 12 inches = 28 mm. 



Habitat. — Walters Station, California, in April (Geo. S. Hutson). 



This is a desert species, represented by one female only. It has 

 somewhat the wings form of Fala ptycophora and belongs to the same 

 general series with that species. The insect is peculiar in the cutting 

 of the median space, by which the ba.sal and s. t. spaces are connected. 

 I know of nothing resembling it nearly enough to cause confusion. 



Oxycnemis fusimacula, sp. nov. 



Ground color bluish ashen gray, more or less black powdered. Antenna; black 

 and white ringed. Head and thorax evenly black-speckled, the posterior scale tuft 

 more blackish at tip. Primaries with the maculation neatly defined, but with a streaky 

 appearance due to the fact that the veins are generally marked with white scales in 

 the darker areas and with black scales in the paler areas. Basal space paler than the 

 rest of the wing. Basal half line black, single, sometimes obscured. T. a. line single, 

 slender, black, with a prominent outward angulation centrally, and an outward bend 

 below the internal vein. T. p. line slender, black, its inception on the costa obscured 

 by a white and black streaking, inwardly oblique, with a somewhat abrupt though 

 slight incurve below the cell. S. t. line is a diffuse whitish shade from the apex to 

 the anal angle, irregular and variably defined. An incur\'ed blackish shading starts 

 from the costa within the apex, crosses the t. p. line, outwardly marks the reniform 

 and ends on the median vein : forming the most prominently contrasting feature of the 

 wing. There is a black terminal line, and the long, gray fringes are narrowly cut 

 with white opposite the veins. Claviform white-ringed, paler than ground, extending 

 from the angle of the t. a. line nearly or quite across the median space, the pointed 

 tip often touching the t. p. line. The ordinary spots are fused and margined by a 

 narrow white line which, at the upper angle of the reniform breaks into a series of 

 white rays extending to the costa inside of the curved blackish shade already described. 

 Secondaries white at base, becoming smoky outwardly, more so in the female, the 

 veins a little soiled. There is a smoky terminal line and the fringes are somewhat 

 marked with smoky. Beneath, primaries blackish, the fringes prominently cut with 

 black and white. Secondaries white, a little powdered over costal region. Expands 

 .90-1.00 inch = 23-25 mm. 



Habitat. — Quartzsite, Yuma Co., Arizona, in March ; Walters Sta- 

 tion, California, in April (George S. Hutson). 



One male and seven females in good condition ; all desert collec- 

 tions. The species is close to advena Grt.; but that species has the 

 t. a. line upright and the ordinary spots subequal, with included 

 dots. The prominent angle in the t. a. line of the new species and 

 the long, fused, white-ringed ordinary spots, will form good distinc- 

 tive characters. The dark subapical shade is the most obvious feature 

 and quite characteristic. There is very little variation in the series
